POSITION
Determines if this TSU is at the head of a chain of units
(directly connected to the modem or PC). The head of the
chain is referred to as the Master Unit. Units down the chain
are referred to as Slaves or a Slave Unit.
The setting of the position selection is necessary only when
using a modem, in which case the head unit should be
Master. For all other cases, select SLAVE. (The Master is in
charge for control of the modem.)
Choices: MASTER; SLAVE
MODEM INIT
The TSU is capable of initializing a modem. This menu
selection is used to effect this initialization and should be
selected only when the choice above designates the TSU as
the MASTER. Prior to modem initialization it should be
physically connected to the TSU and the power turned on. At
this point, an industry-standard AT command string is used
to initialize the modem. The string is also used following
future power-up sequences.
Choices: ENAB - Enable; DISA - Disable
